2004 Hyundai Grandeur spark plugs replace

DRIVING YOUR HYUNDAI 2- 17
C160F01A-AAT Check Spark Plugs and Ignition System Inspect your spark plugs as described in Section 6 and replace them if neces-sary. Also check all ignition wiring and components to be sure they are not cracked, worn or damaged in any way. C160G01A-GAT To Keep Locks from Freezing To keep the locks from freezing, squirt an approved de-icer fluid or glycerineinto the key opening. If a lock is cov- ered with ice, squirt it with an approved de-icing fluid to remove the ice. If thelock is frozen internally, you may be able to thaw it out by using a heated key. Handle the heated key with careto avoid injury. NOTE: The proper temperature for using the immobilizer key is from -40°C to80°C. If you heat the immobilizer key over 80°C to open the frozen lock, it may cause damage to thetransponder in its head.
C160D01A-AAT Check Battery and Cables Winter puts additional burdens on the battery system. Visually inspect thebattery and cables as described in Section 6. The level of charge in your battery can be checked by your Hyun-dai dealer or a service station. C160E01A-AAT Change to "Winter Weight" Oil if Necessary In some climates it is recommended that a lower viscosity "winter weight" oil be used during cold weather. SeeSection 9 for recommendations. If you aren't sure what weight oil you should use, consult your Hyundai dealer.
C160I01A-AAT Don't Let Your Parking Brake Freeze Under some conditions your parking brake can freeze in the engaged posi- tion. This is most likely to happenwhen there is an accumulation of snow or ice around or near the rear brakes or if the brakes are wet. If there is a riskthe parking brake may freeze, apply it only temporarily while you put the gear selector lever in "P" (automatic) or infirst or reverse gear (manual transaxle) and block the rear wheels so the car cannot roll. Then release the parkingbrake.
C160H01A-AAT Use Approved Anti-Freeze in WindowWasher System To keep the water in the window washer system from freezing, add an approved anti-freeze solution in accordance withinstructions on the container. Window washer anti-freeze is available from Hyundai dealers and most auto partsoutlets. Do not use engine coolant or other types of anti-freeze as these may damage the finish.

4. Turn the radiator cap counterclock-
wise without pressing down on it, until it stops. This relieves any pres-sure remaining in the cooling sys- tem. And remove the radiator cap by pushing down and turning coun-terclockwise.Now fill the radiator with clean dem-ineralized or distilled water. Con- tinue to add clean demineralized or distilled water in small quantitiesuntil the fluid level stays up in the radiator neck. G050D01L

SPARK PLUGS
Your engine was originally equipped
with platinum-tipped spark plugs. (If installed)
Platinum-tipped spark plugs will last
longer than conventional type sparkplugs and can be identified by blue lines on the ceramic shell.Unleaded: 1.0 ~ 1.1 mm (0.039 ~ 0.043 in.) Leaded: 0.7 ~ 0.8 mm (0.028 ~ 0.032 in.)

Replacing the Spark Plugs
The spark plugs should be changed
at the intervals specified in the ve- hicle maintenance schedule in Sec- tion 5 or whenever engine perfor- mance indicates they should bechanged. Symptoms that suggest poor spark plug performance include en- gine misfiring under load, loss of fueleconomy, poor acceleration, etc. When spark plugs are replaced, al- ways use spark plugs recommendedby Hyundai. The use of other spark plugs can result in loss of perfor- mance, radio interference or enginedamage.
NOTE:
o When replacing the spark plug, Genuine Hyundai ReplacementParts are recommended. Recommended Spark Plugs:
NOTE: Do not clean or regap platinum- tipped spark plugs.
o Spark plugs should be tightenedfirmly. Overtightening can dam- age the threads in the aluminum cylinder head. Also, leaving themtoo loose can cause the spark plug to get very hot and possi- bly result in damage to the en-gine.
o It is recommended that spark plugs be changed by an autho-rized Hyundai dealer.
